Alan Burchill has written a blogpost about removing notification about backup from the action center in Windows 7.
Since the post shows what you can really do with GPP I think this was worth linking to direct.

This is a quite common question about Group Policy Preferences so I’ll post it here and maybe someone will benefit from the information.

Scenario:Trying to create a shortcut to a fixed drive letter using Group Policy Preference that points to a location on the network. After login there is no shortcut created and if you look in eventlog you see an error “0×80070002 The system cannot find the file specified”. If you run GPupdate /Force the shortcut is created.

This is an issue where it’s trying to create the shortcut before the drive’s are connected and Windows can’t create new shortcuts to locations not connected.

Workarounds:

Create the shortcut using UNC-path

Create the drives and shortcuts using logonscript

Create a scheduled task (using GPP) to run GPupdate after user logon or use logonscript to run GPupdate

A new Knowledge base has been released with a hotfix for solving problems if you still are using adm-templates in GPO and are using Windows 7 or Windows Server 2008 R2.

When you do a settings report of a GPO which contains references to an adm-template (not admx-template) and for some reason this adm-template doesn’t exist in the default paths anymore (you may have cleaned them out) you get “Extra registry settings” in the report instead to show these settings.

Using Windows 7 or Server 2008 R2 when trying to see SRP settings in GPMC you get an error.

Microsoft has released a hotfix

Error message occurs when you use GPMC to view a software restriction Group Policy setting in Windows 7 and in Windows Server 2008 R2: “An error has occurred while collecting data for Software Restriction Policies”http://support.microsoft.com/kb/981750
